GAITHERSBURG, Md. (WUSA9) -- The Gaithersburg Sam's Club that was hit by a car on Tuesday afternoon is clean, stocked and open, say store representatives. The reps say the cafe will open once they get approval from the Montgomery County Fire Marshall, who they expect visit the store on Wednesday morning.

One person was critically injured after a car crashed into the Sam's Club at the 600 block of N. Frederick Avenue in Gaithersburg, police said.

WUSA9's Bruce Johnson was on the scene. Subinoy Mazumdar, a 77-year-old male drove a gold 2002 Buick LeSabre into the building, Montgomery County Police said.

When the car entered the building, it hit Thaan Buithuan, a 33-year-old man, who was transported to the hospital with non-life threatening injuries.

Police said the car also struck a 76-year-old man identified as Dimas M. Chavez, and caused critical injuries, including the amputation of his leg by the vehicle.

Witnesses told Bruce Johnson that the driver "went off" and drove into the building.

The car struck Sheila R. Orellana, who suffered minor injuries, as she was walking in the parking lot with her three-year-old and one-year-old children. The children were not hurt, police said.

The driver of the vehicle was not injured and was interviewed by detectives, Montgomery County Police said.
